I want to make a shaft with a notch, act as a CAM, the follower is a roller on an arm,
Would appreciate a reply on this, posted 3 days ago and no reply.
You didn't need to make a new thread, you could have just commented in your original one to bring it up the list some more.
Making a shaft with notch a cam
If you're not getting any responses it's probably due to a lack of detail of what the problem actually is.
Sounds simple enough, what's the problem?
Can you try Cut Swept feature with Solid Swept option?
Adding some screenshots and a file in a neutral format (Parasolid, STEP) increases the chances of getting help. Not all have the same SW version.
As others have stated, more detail than this part is required to understand your issue:
Also, the thread operation is incomplete:
Open the the thread operation and check Offset and enter an offset to start the thread off the end of the shaft.
Click the arrows button to switch the direction of the offset.
If this is a thread, I think it is necessary to add a chamfer

Agree however the SW Thread tool, without real world thread lead in/out, is also incomplete and many SW users don't know what realistic thread representation looks like or they don't care.
I cared, but thought it something I had to learn to accept. In the Pencil & Vellum days, it was dashed lines, having the threads more visually correct than in those days, was a leap forward. Now with Kevin's guidance I won't be making that mistake any more.
You folks are great, so glad that I can get help from all of you.
Ken Brunskill If you want or need thread realism here’s a link that might give you ideas.
In the initial post, Solidworks seemingly asks for user input about lead in/out enhancements then failed to incorporate anything into the SW Thread Tool that users need. As far as I know, nothing in the tool has been enhanced or corrected since it was introduced.
The file I uploaded in that topic shows realistic examples for tapping, internal thread milling, and external single point lathe threading (chasing). The single point threading example in my part replicates what we do in the shop where the full thread profile needs to stop abruptly at a dimension or a shoulder for maximum engagement with the mating thread. In other words, the least amount of imperfect thread possible for both external and internal threads.
Here is the zip file of that subassembly,
